Relative Path And Accessing Text Files?
May 1, 2011
I have created a sub folder (named 'Data') under my project through the solution explorer. I also have created a text file (data.txt) inside the new sub folder. This text file is used to store information such as settings and connections.
I can check the file using the full path. However, I want to avoid errors such as moving the project folder to a different location. Is there anyway to check using a relative path? File.Exists("~Datadata.txt")
Or is it better to create it under Application.StartupPath?

I am trying to read and display a file using MapPath as follows :
Response.ContentType = "Application/pdf"
Dim FilePath As String = MapPath("../Document/123.pdf")
Response.WriteFile(FilePath)
Response.End()
This procedure will work fine and display in the browser. However, if I save the file to C:Document123.pdf, how can I access this file using relative path in MapPath function. Is there an option to access the file which is saved out of IIS server? I am using vb.net 2003.

Say URL1: http:[url].....
RelativePath: ../../hello.htm
Hence absolute path is http:[url].....
Is there a function that do that?

I'm trying to open a text file in a program I've created but it won't work unless I specify it as an absolute file path. I can't seem to make a relative path name.

I'm coding this neat little project that's kind of a hack into the SanDisk U3 Cruzer's ability to have both a CDFS and FAT32 File System. This is helpful because the program is burned to the CDFS (It's basically slip streamed as an .ISO in place of the original U3 .ISO), and the settings files (which I've developed as text files) are placed on the root of the flash drive. The program itself is VERY simple actually, except I'm having a slight issue that's really driving me insane:
The drive path of the Flash Drive won't be the same from computer to computer. I.E... The files are "UAI.txt" and "UInfo.txt". The root of the drive on my comp is "I:", but on my laptop is "F:". So if I program the path from my computer as the absolute path, an exception is thrown when the path changes on another computer. I cannot have this happen. It is probably THE MOST crucial element to this program. How can you save and read info if you can't find the files? =P
So I've gone through so many threads and forums trying to find a batch of code to allow me to make the path relative. I've found the following code (modified, of course). It works PERFECT in Debug, but throws an exception once packaged to the CDFS partition:

I'm trying to write a little Jukebox application in VB Forms, and I need the pathnames of the sound files (inTracks"Insert Name Here") to be relative instead of absolute, so that it may work on a different computer to mine. At the moment, I am testing with the simple Soundplayer class, and the single line of code to play a song is this: My.Computer.Audio.Play("inTracks" & txtCurrentlyPlaying.Text) It works when, instead of inTracks, I put the full pathname (C:Documents And Settings etc.), but not when I try a relative path such as this.

I have a form with a tabbed control on it. Each tab in the control simply loads an existing file in a reader to display to the user. I have added the files in a folder in my project. When I debug it works great. However, when I publish and move it to another computer, the program runs fine but none of the files show in the tab control tabs. The files do come with the solution when I publish.[code]I know there is a way to make the file path "relative" but I cannot figure out how and there really isn't many resources available to explain how this can be done.

I need to play a sound file: Soundsopen_creaky_door.wav"
However the code only works if I specify the EXACT location:
My.Computer.Audio.Play("c:soundsopen_creaky_door .wav")
Is there a way I can set the relative path to something like this?
My.Computer.Audio.Play("soundsopen_creaky_door.w av")

In VB.net when loading in XML documents using System.Xml.Xmldocument is there a way that I can specify a relative path to the file?[code]...
The XML doc I'm trying to load is in the same directory as the VB class. But I'm having trouble accessing it without using a full path to the XML doc.

I have completed my VB project using vb 2008 express edition..I am not able to create a set up file for my project and I think it is because of the file path i have provided in my program
dbSource = "Data Source = C:Documents and SettingscfadminDesktopLead_managementLead_Management_ProjectLead_Management_ProjectLondon.mdb"
The above path is a fixed path which connects my program to the database. Now when I create a set up file and try to run on another machine it wont recognize this path . have placed the database in the same folder that of the program.

In vb.net, when writting an application, I want to access a batch file that has been added to the project. My question is how to I find the relative path of this file to access it? I have used relative path on the ASP.NET side, but not on the application side. The properties that I am finding regarding the current directory and running directory and the likes are all for the bin directory its in. While I can use the CurrentDirectory() property and go up two parents (....) in the development environment, when I install the application, the structure is not the same. As in the output is in a single folder, not tiered.
Example. c:projectsMyAppindebugMyApp.exe is the running directory
My file I want to access is at c:projectsMyAppvalidate.bat
so "c:projectsMyApp" is what I am trying to capture.

I was doing window services where I'm generating txt files in target path based on some details from a database. I was getting same file name in the place of sec variation required so that I can avoid duplicates over there.
Code:
using (transactionscope scope = new transactionscope ) {
string nowtime = datetime.now.today.tostring(HHMMss) // it was working fine
}
File should be generates by specific file naming convention !! ex:hhmmss >>> no millisecond.

I need to access a file path, but a part of the path is different on each PC. Mozilla creates a random profile name for each PC it is installed on. I can get most of the path through environment variables. I need to access the files inside of the default profile, but can't since I'm not sure how to access it.
Here's an example of the file path:
'C:Users\%USERPROFILE%AppDataRoamingMozillaFirefoxProfilesxxxxxxxx.default'
The only thing that stays the same with the profile name, is the '.default' part.

I'm using VS2010 Express, and Visual Basic.I'm trying to make a fancy drop down list next to text box. When the user enters some text in the text box, the program will look up values in a database and show them in a list box (to easily select some existing items).The list box is in a panel control, which is initially hidden (and I have other stuff in the panel for other features.)If the query finds some entries in the database, I want to show the list box (and the panel and everything in it) and then move the panel so its top left location aligns with the top right location of the text box.I can get the panel to show (visible = true) but I can't get it to line it up with the top right edge of the text box.I'm using this code to move the panel after I set it visible.

I need to show a grid of saved projects (compare "orders") in a datagrid, where the projects are saved in an Access 2000 database with a similar schema as follows:
ID Name Country_ID Plant_Type
1 'Test' 1 1
2 'Second' 2 2
Let's call the file "Projects.mdb". This is then showed in the datagrid as:
ID Name Country Plant Type
1 'Test' 'Germany' 'Free Range'
2 'Second' 'France' 'Inclined Roof'
where the countries and "Plant Types" are fetched from a different table in a different .mdb file (also Access 2000, call it "Language.mdb", although there is a lot of different background data in it), depending on the current user's language preference. It is unfortunately not an alternative to merge these .mdb's into one file.
To be able to show the datagrid I have so far linked the tables from "Language.mdb" into "Projects.mdb", but this screws up when the project is being installed on another computer with the .msi file i created (we'd like to have this easily packaged and installed), as the "Language.mdb" doesn't exist on the linked path on the target computer (Basically the problem here).
I can come up with the following solutions:
Force all users to install on the same path, so that the links will work (undesirable)Use connection strings in the query as shown here on MSDN (still trying this out, but I need to work on the details)make a post-install script that relinks the tables according to the correct path.
